How to Make Power-Wash Soap

Buying power wash soap can be expensive, which is why people often make their own with a few common ingredients in their home. Pressure washers help thoroughly clean outside areas such as concrete and home exteriors. The addition of soap with the water ensures that stains remove easily by breaking them down. You will save money by making your own power-washer soap that will effectively remove stains and mould.

Pour a quart of bleach into a large bucket. Wear gloves and a face mask to protect your skin and lungs from the bleach.

Add 1/3 cup of powdered dish detergent. Stir slowly until the detergent dissolves into the bleach.

Pour in 2/3 cup of powdered household cleaner. Stir the mixture slowly to dissolve the powdered household cleaner, trying not to create suds.

Add a gallon of water to the mixture slowly to prevent it from splashing up at your face.

Place a tarp over any areas in your yard that the cleaning solution could harm. These include but are not limited to flowers, shrubs and trees.

Pour this newly mixed power-washer soap into the pressure washer. Follow the manufacturer’s directions.


Pre-wash the area with plain water before using the pressure washer to help loosen debris. Always rinse the pressure-washed area afterward to remove the pressure-washer soap.
